Followed them for a while because I do think their core competency had a lot of value (having a rap lyrics site with no pop up ads alone pretty much did that...)
Kind of a bummer that they raised at such a high valuation and repeatedly set their sights on scaling to areas with minimal chance of success.
Also always thought about how the need for annotations is probably a lot lower in other genres / types of text content. I rarely need an abridged Wikipedia-level explanation of who Donald Trump is, but these kinds of clues tend to be key in interpreting the wordplay of hip hop.
